Use the ``watch_file(filename)`` function to cause a reload/restart for other other non-Python files (e.g., configuration files). If you have a dynamic set of files that grows over time you can use something like:: def watch_config_files(): return CONFIG_FILE_CACHE.keys() paste.reloader.add_file_callback(watch_config_files) Then every time the reloader polls files it will call ``watch_config_files`` and check all the filenames it returns.
